As shown in
The sequence of mechanical actions of the entire device:
The fixing frame 20 is placed in a pipe for removing sludge. At this time, the driving motor 49 is started to drive the third rotating shaft 51 to rotate, thereby driving the spline shaft 28 to rotate, thereby driving the second gear. 14 turns, thereby driving the first gear 13 to rotate, thereby driving the threaded rod 26 to rotate, thereby driving the left and right two moving blocks 24 to move back and to the left and right, thereby pushing the supporting block 22 to move, thereby The roller 21 is pushed into abutment with the tube wall, and the jet thruster 61 is started at this time. At this time, the jet thruster 61 is ejected out of the fixed frame 20 through the exhaust chamber 12, thereby pushing the jet propeller 61. The fixed frame 20 moves along the pipeline to the inside of the pipeline. When the fixed frame 20 moves, the pull wire 56 is pulled deeper into the interior of the pipeline. At this time, the second sliding rod 30 loses the abutment of the fixed frame 20. At this time, the first Under the action of the resetting device 299, the two sliding rods 30 move to the left and move out of the inclined hole 35. At this time, the third sliding rod 34 moves into the sliding cavity 36 under the action of the fourth spring 33. When the fixed frame 20 moves, the pulling wire 56 is straightened When the fixed frame 20 continues to move, the sliding block 62 moves to the left, and the sliding block 62 moves to the left to move the first rack 47 to the left, thereby driving the sliding block 62 to move to the right. Thus, the output shaft of the driving motor 49 is driven to move out of the spline hole 50, and the output shaft of the driving motor 49 continues to move right into the spline sleeve 45 and cooperates with the spline sleeve 45. The locking groove 37 is aligned with the third sliding hole 32, the third sliding rod 34 is inserted into the locking groove 37, and the pull wire 56 pulls the first sliding rod 18 out of the card slot 19, at this time The fan-shaped scraper 58 abuts against the pipe wall under the action of the third spring 59, at this time, the jet propeller 61 is closed, and the driving motor 49 is started to drive the spline sleeve 45 to rotate, thereby driving the The second bevel gear 43 rotates, thereby driving the first bevel gear 41 to rotate, thereby driving the reel 38 to rotate, thereby winding the pull wire 56 on the surface of the reel 38, thereby driving the fixing. The frame 20 approaches the fuselage 10, and the fan-shaped scraper 58 contaminates the inner wall of the pipe at this time. When scraping, the sludge is taken out along the pipeline. When the fixed frame 20 moves to abut with the second slide bar 30, the second slide bar 30 moves to the right to drive the third slide bar 34 out of the place. The reel 38 is described. At this time, the sliding block 62 is moved to the right under the action of the spline sleeve 45, so that the first rack 47 is moved to the right, so that the fixed block 63 is moved to the left, thereby driving the The output shaft of the driving motor 49 is splined to the spline hole 50 again, and the device returns to the initial state at this time.
